A. Vidyadhar and R. Singh INTRODUCTION Froth flotation is a process used to separate minerals, suspended in liquids, by attaching them to gas bubbles to provide selective levitation of the solid particles. It is most extensively used process for the separation of chemically similar minerals, and to concentrate ores for economical smelting.Froth Flotation Process - Mineral Processing & Metallurgy,Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005 Download as PDF About this page Froth FlotationFroth Flotation Handbook - Mineral Processing & Metallurgy,28-03-2016· Flotation, as the term is applied to ore concentration, means the separation of one of the constituents of an ore from the remainder by causing it to float at or above the surface of a pulp consisting of the finely pulverized ore and water. Minerals that float Minerals that float have a metallic, adamantine, or resinous luster.Extraction of Zinc: Froth Floatation Process, Roasting,,30-11-2021· As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K. The impure zinc obtained after reduction is purified by electrolysis.

The term is loosely used to describe any preparatory stage prior to flotation. Different systems require conditioning for different purposes: while one mineral may require an oxidative conditioning stage, another may need to have the mineral surface cleaned or reduced by an acid wash.1 Froth Flotation – Fundamental Principles,After carrying out a froth flotation separation, the products are as shown in Table 1.

Why is the froth flotation method only used for sulphide ores?
Answer (1 of 8): In froth floatation process, advantage is taken of prefferential wetting of ore particles by oil and gangue particles by water. Pine oil or eucalyptus oil has tendency to wet metal sulphides. Thus sulphide ore is present in oily froth whereas gangue particles settle at the botto...Which of the following ores is concentrated by the froth,,Answer: The third one down on the left.
